Mass effect 2 Overlord DLC Crash

I'm playing Overlord with an imported character from ME, and my PS3 has crashed twice before entering the satellite dish in Hermes Base.

Solved this part by having my squadmates (Miranda and Jacob) take out all the Geths at the entrance while Shepard stayed in cover and did not fight.

After entering the dish, the squad sprinted for the upper levels, cleared all the Geth Rocket Troopers and blowed the first capacitor, but while en route to the second, my PS3 crashed again.

I'm afraid to subject my PS3 to another crash, so can please anyone give me some advice? I would like to completed this mission, but the odds are not looking good.

I'm saving to the cloud through PSN Plus, I have another 2 careers which both cleared Overlord without problems (both not imported from ME); I'm 8 hours into this run, and have not completed any recruitment mission (except Zaeed).

Thank you all in advance.
